STONE-SAWING MACHINE.

Specification of Letters Patent.

Patented Nov. 20, 1906.

To all whom, it may concern.-

Be it known that I, EDsoN T. POLLARD, a citizen of the United States, residing at Rutland, in the county of Rutland, State of Vermont, have invented certain new and useful Improvements in Stone-Sawing Machines, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to a stone-sawing machine, and particularly to a secondary saw disposed in substantially a horizontal plane and adapted to cooperate with the vertically-disposed saw, so as to completely remove the portion of the block to be sawed.

The invention has for an object to provide a saw disposed upon a horizontally-traveling carriage upon one side of the platen of a stoneworking machine, together with means for adjusting the saw and its carriage toward and away from said platen.

A further object of the invention is to provide means for vertically adjusting said saw and driving the same in any of its adjusted positions.

Another object of the invention is to provide means for adjusting this saW at an inclination to a horizontal plane, so as to remove the portion of the material with a diagonally-disposed face thereon.

Other and further objects and advantages of the invention will be hereinafter set forth and the novel features thereof defined by the appended claims.

In the drawings, Figure 1 is an end view showing the saw applied to the frame of a stone-sawing machine. Fig. 2 is a side view thereof with parts of the side saw in section on line 2 2, Fig. 1. Fig. 3 is a horizontal section on line 3 3, Fig. 2. Fig. 4 is a side view of the tool-holder of a stone-sawing machine, showing the means for vertically adjusting the same; and Fig. 5 is a diagrammatic view indicating the cut or check adapted to be made by the use of the two saws.

Like numerals of reference indicate like parts throughout the several views of the drawings.

The construction of side saw herein shown is adapted to cooperate with the work-carrying platen of any character of stone-dressing machinery but for the purpose of illustration one of the most applicable forms thereof is herein shown and described in connection with a stone-sawing machine having a vertically-disposed saw of the usual type.

In the form of stone sawing machine shown the numeral 1 indicates the base thereof, upon which the platen 2 is slidably mounted in the usual manner to carry the work, while extending from the base at each the usual saw-holder, comprising opposite side is standards 3. These standards are connected together by cross-bars 4, upon which the arms 5, carrying the vertically-disposed saw 6 are mounted and adapted to travel. This saw 6 is constructed for adjustment laterally of the platen by means of the screws 7, engaging the saw-carriers 5, as indicated by dotted lines in Fig. 1, and provided at one end with the bevel-gear 8, meshing with a corresponding gear 9, carried upon the shaft 10, which is provided with any suitable crank 11 for adjusting the screws 7 upon each side of the standard simultaneously.

The arbor or shaft of the saw 6 is provided with a driving-pinion 12, as shown in Fig. 4, and meshing with a cooperating pinion l3, slidingly splined upon the shaft 14 of the driving-motor 15, disposed in fixed position. The cross-bars 4, which support the saw-carriers, are adjusted vertically of the standards by means of screws 16 at opposite sides thereof, provided at their upper ends with bevel-gears 17, meshing with cooperating pinions 18, carried by a shaft 19 and adapted to be operated by a driving-pinion 20, cooperating with a gear carried upon the adjustinglever 21.

By the means hereinbefore described the vertically-disposed saw may be adjusted laterally of the platen and also vertically toward and from the same and driven in any of its adjusted positions.

The side or checking saw 22 is mounted upon a base-plate 23, adapted for attachment to the side of the base 1 in any desired mannerfor instance, by means of bolts 24. This plate 23 is provided with dovetailed ribs 25, adapted to be engaged between similar ribs 26, depending from the carriage 27. This carriage is provided with an elongated bearing box or sleeve 28 upon its upper surface, from which an upwardly-extended rib or flange 29 is disposed and provided with a segmental adjusting-slot 30. Disposed in this bearing 28 is the shaft or axis 31 of the saw-carrier 32, which is disposed at substantially a right angle thereto, as shown in Fig. 2. This carrier is formed with an interior chamber 33 adapted to receive the means for vertically adjusting the saw, and with a lug or projection 34, extending into contact with the flange 29 and adapted to be secured thereto in its adjusted position by means of the bolt 35 or other suitable securing means.

The saw may be vertically adjusted in its carrier by any desired meansfor instance,

the threaded screw 36, mounted in the interiorly-threaded nut 37, having upon itsouter periphery a worm-gear 38, adapted to engage the driving-worm 39, provided with the oper ating-handle and mounted in the lugs 41., carried by the nut-casing 42, threaded upon the upper end of the saw-carrier 32. The driving shaft or arbor 43 of the saw 22 is journaled within the screw 36 and held in any desired manner-for instance, by means of adjusting-nuts 44 at its lower end and the usual arrangement of clamping-nuts 45 at the upper portion thereof, where the saw is held. For the purpose of driving this saw various constructions may be used; but I have herein shown the shaft or arbor 43, which is provided with the angular recess 46 therein and adapted to fit a similarly-formed portion 47 of the driving-shaft 48, which is provided with a bevel-gear 49 at its lower end adapted to mesh with a similar gear 50, carried upon the shaft 51, disposed within the bearing 31 of the saw-carrier and having at its opposite end bevel-gear 52, meshing with a corresponding gear 53, splined upon the shaft 54, which is provided with a driving-pulley of any desired character, to which power may be applied from any source. This splined connection permits the gear 53 to slide upon its shaft 54 in the adjustment of the carriage, and the carriage is provided with an arm 66, embracing the shaft 54 at one side of said gear, so as to retain it in meshing contact with its companion gear.

Various means may be used for adjusting the side saw toward and from the side of the platen, but that herein shown has been found desirable and comprises a threaded lug 56,

Fig. 1, depending from the carriage 27 and adapted to receive the adjustin -screw 57, mounted in the base-plate 23. T is screw is provided at its outer end with a driving-pinion 58, meshing with a cooperating pinion 59, carried by the vertically-disposed shaft 60, having at its opposite end a hand-wheel 61, mounted in a suitable standard 62, rising from the base 23.

In the operation of the invention it will be seen that a great variety of cuts or checks may be effected by the use of this invention, particularly when the side saw is used in connection with the vertically-disposed saw, as shown in Fig. 1. This vertical saw is capable of adjustment laterally of the platen and ver- 6 5 tically toward andfrom the same, while the side saw is also capable of lateral adjustment toward and from the side of the platen and vertically relative thereto. The side saw is also capable of disposition in a plane extending diagonally to that of the platen, so as to provide a beveled or inclined surface upon the work cut, as shown by dotted lines in Fig. 5, while if a right angle is desired the saw may be retained in a horizontal plane, as shown by full lines in said figure. It will therefore be seen that by a proper adjustment of these two saws various forms of blocks or checks may be cut from a block of stone and that the mounting of theside saw is such as to permit its being driven in any of its adjusted positions, and adjustment can also be made while the saw is still rotating, as the adjusting means are independent of the driving connections. When the saw is adjusted in a curved path upon its bearing in the carriage, the drivinggears travel upon. each other, while in a vertical adjustment of the side saw its arbor travels upon the angular portion of its drivingshaft. This invention therefore presents a very convenient, econnomically-c onstructed, and readily-controlled means for driving the horizontally-disposed side saw at one or both sides of the laten of any character of stone-dressing mac inery to which it may be adapted.
